What is a bone injection gun (also known as a BIG)? A bone injection gun was first produced and utilised in paramedicine and medicine in early 2000 as a rapid means of delivering emergency resuscitation drugs, such as adrenaline and atropine into the intraosseous space of the manubrium (lower part of the sternum).

The bone injection gun was designed to be inserted straight into the manubrium during active resuscitation efforts in cardiac arrest for adult patients, however it can also be used to gain intraosseous access into the tibial tuberosity.
